If you have a good relationship with your Local Coin Dealer, they will sometimes give you old copies of the Grey Sheets they have, if they kept them. Mine does whenever I ask. I really don't like the Grey Sheets because it is Coin Dealer's guide to buy and sell which is based more on input from Coin Dealers as to what they want to pay for coins or sell coins for and they do not always take into account most of the actual Coin Market variables (prices realized from the many selling venues, some precious metal fluctuations and even the many Price Guides available). While Coin World's "Coin Values" Guide, PCGS' Price Guide, NGC's Price Guide, Numismedia.com, eBay's Sold Prices and others may give somewhat close pricing on certain coins, the Grey Sheets can be way out in left or right field in comparison.
